Parameters
*4
  Description 
An-□□ 
Frequency command 
Bn-□□ 
Parameter settings can be changed during running 
Sn-□□ 
System parameter settings (can be changes only after stop) 
Cn-□□ 
Control parameter settings (can be changed only after stop) 
 
The  parameter  setting  of  Sn-03  (operation  status)  will  determine  if  the  setting  value  of 
different  parameter  groups  are  allowed  to  be  changed  or  only  to  be  monitored,  as  shown 
below:

*2:When in DRIVE mode, the parameter group Sn-, Cn- can only be monitored if the 
RESET
 key and the 
DSPL
 
key are to be pressed at the same time, 
*3:  After  a few  trial  operation and  adjustment,  the  setting  value  Sn-03  is  set  to  be 
“0101" so as not be modified again. 
*4:The 7200GS/GS510 has 2 groups of monitoring parameters and one group of order  
parameters in addition to the above 4 groups of user parameters. 
Un-□□:Can be monitored by the users under the DRIVE mode. 
Hn-□□:Can be monitored by the users under the PRGM mode. 
*5:On-□□:Order parameters can be monitored and changed by setting Sn-03=1010.
